On the moors

Body movements are stiff, expression doesn’t come across clear, mouth flaps are out of sync. Nice and colourful presentation though

The background looks good and the Monster looks pretty adorable.
But with the open field It felt kind of jarring to have the big monster suddenly behind him, especially when it just cuts to the monster just plainly out in the open without any camouflage. If I'd suggest maybe you could've used the big rocks or bushes as the monsters disguise to surprise the character.
As for the character animation, the lip sync and motion when he's running can be improved with a bit of anticipation or slow in/slow out as of for him just zooming out of the frame.
